BELL-.RINIGI'NG MECHANISM.

SPECIFICATION forming part of Letters Patent No. 528,134, dated Octoberso, 1894. 1

Application filed May 3, 1894. Serial No. 509,937. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM G. ALEXAN- DER, a citizen of the UnitedStates, residing at Bozernan, in the county of Gallatin and State ofMontana, have invented certain new i and useful Improvements inBell-Ringing Mechanisms, and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains-to make and use thesame. I

My invention relates to bell-ringing mechanisms and particularly to suchmechanisms of this kind as are designed for ringing or soundingalarmibells as for instance for indicating the presence of fires incities and towns where the strokes must be positive, uniform and atproper intervals.

The objects of my invention are to produce a simple mechanism to beoperated in any simple manner and which will be positive in itsoperation, uniform in its strokes and will not interfere with the freevibrations of thebell.

Other objects and advantages of the invention will appear in thefollowing description and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings: Figure 1 is an elevation of a portion ofahouse, such for instance as an engine house, the same having a bell andmechanism for sounding the same constructed in accordance with myinvention. Fig. 2 is a detail in perspective of the rotary hammer shaft;Fig. 3, a sectional view through the joint between the same and hammerrods.

Like numerals indicate like parts in all the figures f the drawings.

In the present instance 1 designates the roof-timbers of a house andupon the same I locate a pairof aligning horizontal bearings 2 in whichis arranged for free rotation ahorizontal shaft 3 having at one end abeveled gear wheel 4. In suit-able vertical aligning bearings 5 arrangedin the structure, I journal a vertical operating shaft 6 that leads froma point above the ground floor to the roof and is there provided with abeveled gear 7, a similar gear occupying the lower end of the shaft. Theupper gear 7 intermeshes with the gear 4 of the rotary shaft 3 and thelower gear 7 intermeshes with and is driven by the power gear 8 that isarranged upon a horizontal shaft 9 supported in bearings 10. The gear 8is provided with a handle 11 by which it may be revolved. If desiredother means may be employed for giving motion to the shaft 3 and I. donot limit my invention in thisregard, but have merely illustrated it toshow one manner of operating the mechanism.

Above the inner end of the shaft 3 and supported in any desired manneras for instance by a timber 12 is the bell j Arranged on the end of theshaft 3 is a pair of longitudinal slotted arms 14, theinner ends ofwhich overlap, so that the bar as a whole is freely adjustable by meansof a pair of set bolts 15 and their nuts. The outer ends of the arm 14are slotted or recessed at diagonally opposite points and their cornersare at these points cut away as indicated at 16. Between the walls ofeach recess there are pivoted at 17 hammer rods 18 whose inner ends arerounded as indicated at 19 and whose outer ends are provided with hammerheads 20'. Cushions 21 of rubber areinterposed between the inner ends ofthe rods 18 and the bottoms of the recesses.

The end of the shaft 3 projects through the slots in the arms betweenthe set bolts and for suchpurpose is reduced and threaded at 22, thusforming a shoulder 23 at the inner end of the reduced portion. A nut orwasher 24= is seated against the shoulder and a similar nut or washer 25is against the outer side of the arms and is bound upon by an outer nut26, threaded on the end of the shaft so that the bar as a Whole is fixedupon and must revolve with the shaft.

This completes the construction of the device and the operation is asfollows: As the shaft 6 is revolved so, also, is the shaft 2, the

i do

sition immediately after passing the bell, the return being accomplishedby the spring cushion aided by the centrifugal force.

From the foregoing it will be seen that I provide a very simplemechanism for positively, uniformly and at intervals sounding alarmbells which mechanism is adjustable and therefore adapted to occupydifferent positions with relation to various bells so as to secure thebest results.

What I claim is- 1. In a bell ringing mechanism, the combination of arotary shaft, arranged below and at a right angle to the bell to berung, means for rotating the same, a bar carried by the shaft below thebell, and loose hammer rods pivoted below the bell to the bar andterminating at their outer ends in heads, substantially as specified.

2. In a bell ringing mechanism the combination of a shaft arranged belowat right angles to the bell, means for rotating the shaft, a bar carriedby and arranged at right angles to the shaft and recessed atdiametrically opposite corners, hammer rods having heads pivoted in therecesses below the bell and elastic cushions seated in the bottoms ofthe recesses to support the rods when at an angle to the bar,substantially as specified.

3. In a bell ringing mechanism the combination of a rotary shaftarranged and terminating below'the bell, a pair of slotted overlappingarms receiving and secured to the shaft, set bolts arranged in the slotsat opposite sides of the shaft and headed hammer rods pivoted to theouterends of the bar and adapted to contact with the bell, substantiallyas specified.

4:- In a bell ringing mechanism the combination of a horizontal shafthaving a reduced threaded end, a bar comprising slotted arms overlappedand arranged on said end, washers at opposite sides of the bar, a nut onthe end of the shaft against the outer washer and pivoted hammercarrying rods for the ends of the bar, substantially as specified.

5. In bell ringing mechanism the combination of a lower shaft, means forrotating the same, a bar carried by the shaftand disposed at a rightangle thereto, hammer rods having heads and pivoted to the ends of thebar, stops in front of the rods for limiting their forward movement andcushions in the rear of the rods, substantially as specified.

6. In a bell ringing mechanism, a horizon tal shaft, a gear carriedthereby, a hammer carrying bar arranged on the shaft, hammer rodsloosely pivoted to the ends of the rod, a vertical shaft, gears on theupper and lower ends thereof, a lower power shaft, a hand wheel havingteeth for engaging the lower gear, all combined and operating,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM G. ALEXANDER.
